CHAR & TCHAR 转换

CString strData = _T("ni hao");

int len = WideCharToMultiByte(CP_ACP, 0, strData, -1, NULL, 0, NULL, NULL);

     char* szTarget = new char[len + 1];

     memset(szTarget, 0, len + 1);

     WideCharToMultiByte (CP_ACP, 0,strData, -1, szTarget, len, NULL,NULL);

delete[] szTarget;

CString－>TCHAR*的转化可以用函数GetBuff()

函数原型为：LPTSTR GetBuffer( int nMinBufLength );

CString str("CString");

TCHAR* szMsg = new TCHAR[100];

//其参数为CString字符串的长度

szMsg = str.GetBuffer(str.GetLength());

str.ReleaseBuffer();

delete []szMsg;

szMsg = NULL;

TCHAR*－>CString的转化

TCHAR szTchar[18] = L"TCHAR";  

CString str;  

str.Format(_T("%s"),szTchar);
